摘要：
A continuous transition from tilted to homeotropic alignment at an interface is observed at a temperature T-a for a nematic liquid crystal on cooling toward the nematic-smectic-A phase transition temperature. T-a is found to depend on the treatment of the substrate. The behavior is examined theoretically in terms of a pair of competing easy axes (homeotropic and planar) and the tilt elasticity associated with the growth of surface-induced smectic order.
